It is an objective of the invention of the present application to provide an image display apparatus capable of reducing a change in a display state of a virtual image that depends on a change in a viewpoint position. An image display apparatus according to an embodiment of the present technology includes an emission unit, a diffractive optical element, and an emission control unit. The emission unit emits image light of a target image. The diffractive optical element includes an incident surface and an emission surface, diffracts the image light entering the incident surface, emits the image light from the emission surface, and displays a virtual image that is the target image. The emission control unit controls emission of the image light by the emission unit by using image data generated in accordance with a change in a display state of the virtual image that depends on a change in a viewpoint position.

A three dimensional (3D) display apparatus can include lenticular lenses between a display panel and a viewing angle control film. The display panel can have a curvature. The viewing angle control film can include a plurality of light-blocking patterns between a first control substrate and a second control substrate. A pitch and a height of the plurality of light-blocking patterns can be determined by a curvature radius of the lenticular lenses, a distance between the viewing angle control film and a set viewing region, and a length of the display panel corresponding to the set viewing region. Thus, in the 3D display apparatus, the quality of 3D images provided to a user can be improved.

Provided is an anti-counterfeit label with multi-focus multi-layer depth-of-field images. The anti-counterfeit label is sequentially provided with a multi-focus microlens array layer, a transparent base membrane layer and a microtext array layer from top to bottom in a laminating mode, and a metal reflective layer is arranged under the microtext array layer; the multi-focus microlens array layer comprises microlenses which are distributed in an array mode and have multiple focuses; the microtext array layer comprises one set or multiple sets of subunit pattern periodic ordered arrays. The anti-counterfeit label has the advantages that the microtext array layer can be amplified by 80-800 times by the multi-focus microlens array layer. The anti-counterfeit label is particularly suitable for popular anti-counterfeiting and can effectively improve the anti-counterfeit capacity.

A head-up display apparatus is disclosed. The head-up display apparatus according to one embodiment of the present invention comprises: a display panel; a stereoscopic image filter; and a mirror. The display panel includes a first region in which a first image is displayed and a second region in which a second image is displayed, and the stereoscopic image filter is configured to convert the first image into a stereoscopic image. In an embodiment of the present invention, the first image displayed on the display panel is warped and displayed, thereby preventing distortion of the stereoscopic image when projected on a windshield.
